3.2 Connection

Connection can be made to the right, left or top or rear of the heat pump.

Cut away the cover plate on the side where the hoses are to be connected.

When the opening has been made through the cover plate, carry out the installation as follows:

1. In order to protect the hoses, fasten the protective edging provided around the edge of the opening in the insulation plate. Adjust the length of the protective edging to suit the opening as required.

2. Pass the hoses through the opening in the side cover plates and connect them. Ensure that the insulation covers all parts of the brine connection to prevent ice and condensation forming.

3. Then install the collector system.

You can also connect the primary flow on one side and the return on the other. See the chapter on Measurement details for measurements and dimensions. The pipe between the heat pump and brine loop should not be less than Ø35 mm in dimension.

!

If a cooling module is connected on the side, the opening must be lined with the edge moulding provided to prevent abrasion against the hose.

General Information

3.3 Heat medium side

Connect the heat pump with a dimension of at least Ø35 mm so it can then be joined to a collecting pipe. The non-return valve and dirt filter are 1¼".

The dimension of the collecting pipe depends on the installation.

Route the pipes so that no other highest point is present where air can collect and obstruct circulation. If however this cannot be done, provide this highest point with an automatic bleeder.

NOTE! Only 1 heat pump/ cooling module are to be connected to the accessory Mixing valve.

3.5 Brine system

The brine system, i.e. the ground collector loop, must be assembled and connected by a qualified tradesman in accordance with current regulations and design guidelines.

Extreme care must be taken to ensure that no dirt gets on the collector hoses, which must be washed clean before being connected. The protective caps must remain in place at all times while work is in progress.

The temperature in the brine system can go below 0°C. This is why it is important not to use any water-based lubricant etc. during installation. It is also important that all the components are insulated against condensation to prevent the build-up of ice.

Valves

To facilitate servicing of the cooling unit, shut-off valves should be fitted to both the incoming and outgoing connections. Fit bifurcated valves so that you can fill and bleed the collector circuit later on.

Bleeding

The collector circuit must not contain any air. Even the smallest amount of air can jeopardise the heat pump’s operation. See the section Filling and venting below.

Insulation against condensation

All pipes in the brine system must be insulated against condensation to prevent the possibility of severe build-up of ice and condensation.

104 c T c

103


General Information

Filling and venting

Mix water and antifreeze solution in an open vessel. Connect hoses to the shut-off valves (98a and 98b) as shown in the figure. Connect a powerful external pump (101) for refilling and bleeding. Then reset the three-way valve

(100) and open the valves (98a and 98b) so that the brine passes through the mixing container (102). Also make sure that the valve (98d) is open.

For start-up of the brine pump, see the relevant manual for the EcoPart’s controller.

Allow the brine to circulate in the system for a long period of time until it is completely free of air. There could still be air in the system, even though no air accompanies the liquid out. Reset the 3-way valve (100) so that any remaining air can come out.

Bleed the level vessel (96) by loosening the plug on the top of the level vessel.

Now close the valve (98a) while the filling pump continues to run. The filling pump (101) now pressurises the system. Also close the valve (98b) and shut off the filling pump.

If the level in the level vessel is too low, close the valves (98c) and (98d).

Unscrew the plug and fill the vessel to around 2/3 full. Screw the plug back in and open the valves (98c) and (98d).

Post-installation check on brine system

After a few days, you must check the fluid level in the vessel. Fill if necessary and close the valves (98c and 98d) when filling.

Expansion vessel/level vessel

The vessel should be fitted to the incoming line from the borehole or ground loop, at the system’s highest point. Bear in mind that the tank can produce condensate on its exterior. Fit the safety valve (105) as shown in the schematic diagram and fit a suitable plug to the top of the vessel.

If the vessel cannot be fitted at the highest point, a closed expansion vessel must be fitted.

Filling kit with dirt filter

Arrows on the valve housing indicate the flow direction. Close valves (98c and 100) when cleaning the filter. Unscrew the filter cap and flush the filter clean. When refitting, the pin under the filter holder should be fed into the designated hole in the filter housing. Top up with a little brine, if necessary, before fitting the cap.

The filter should be checked and cleaned after a short period of operation.

Brine

The brine circulates in a closed system. The fluid consists of water and antifreeze solution. Sentinel R500 & R500C are recommended for use in the brine circuit on all CTC EcoHeat/Part heat pumps. The glycol is mixed at a concentration of slightly less than 30%, which is equivalent to fire risk class

2b and a freezing point of around -15°C.

It is a CTC recommendation that around 1 litre of brine/glycol is required per metre of collector hose, i.e. around 0.3 litres of antifreeze solution will be needed per metre of hose, for a hose diameter of 40 mm.

!

Check the dirt filter after bleeding has been completed.

!

The fluid must be thoroughly mixed before the heat pump is started.


Air pockets

To avoid air pockets, make sure that the collector hoses constantly rise towards the heat pump. If this is not possible, it must be possible to bleed the system at the high points. The filling pump usually manages smaller local height discrepancies.

Checking brine difference

When the heat pump is running, regularly check that the temperature difference between incoming and outgoing brine temperatures is not too large. If there is a large difference, one of the causes may be due to air in the system or a blocked filter. If this is the case, the heat pump triggers the alarm.

The alarm factory setting is 7°C, but 9°C is permitted for the first 72 hours while the compressor is running, as microbubbles in the system can reduce brine flow.

General Information

4. Electrical installation

The installation and heat pump connection must be done by an authorised electrician. All wiring must be installed according to valid requirements.

• The CTC EcoPart 3 x 400 V must be connected to 400 V 3N~ 50 Hz and protective earth.

• The CTC EcoPart 1 x 230 V must be connected to 230 V 1N~ 50 Hz and protective earth.

The minimum group fuse size is indicated by the Rated current under

Technical data.

Use the cable provided to connect to the power supply. The product is already wired inside.

Safety switch

The installation should be preceded by a omnipolar safety switch

(Category III), which ensures disconnection from all electric power sources.

4.1 Alarm output

The EcoPart is provided with a potential-free alarm output which is activated if any alarm is active in the heat pump. This output may be connected to a maximum load of 1 A 250 V AC. An external fuse should also be used. Cable approved for 230 V AC must be used for connecting this output, irrespective of the load that is connected. For connection information, see the wiring diagram.

Detailed illustration from wiring diagram

4.2 Groundwater heating

Groundwater, too, can be used as a heat source for CTC's heat pumps.

The groundwater is pumped up to an intermediate heat exchanger that transfers the energy to the brine liquid. It is important that an intermediate heat exchanger is installed in the system. The intermediate heat exchanger prevents the product evaporator from becoming damaged due to deposits from groundwater particles and minerals, which could otherwise involve expensive work on the product's refrigerant system. Water requirements analysis should always be undertaken for intermediary heat exchangers.

Local regulations and permit requirements must be taken into account. The return water is discharged elsewhere, to a drilled return flow well or similar.

The brine pump and groundwater pump must be connected to run simultaneously in order to avoid risk of freezing.

Also pay attention to the intermediary heat exchanger supplier's instructions.

The last heat pump (the cooling module) connected in series must be partly terminated and the shielding in the communication cable must be connected to earth. See below.

5.3.1 Terminated position

The last heat pump connected in series must be terminated. This is achieved with a DIP switch located on the circuit board inside the electrical cabinet.

The top cooling module A2 is terminated at the factory, i.e. DIP switch 2 is in the ON position. In the bottom cooling module A1, DIP switch 2 is in the OFF position. Make sure DIP switch 2 is in the ON position on the module that is to be terminated.

General Information

7. Operation and

Maintenance

When the installer has installed your new heat pump, you should check together that the system is in perfect operating condition. Let the installer show you where the power switches, controls and fuses are so that you know how the system works and how it should be maintained. Bleed the radiators (depending on type of system) after around three days of operation and top up with water if required.

7.1 Periodic maintenance

After three weeks’ operation and then every three months during the first year. Then once a year:

• Check that the installation is free of leaks.

• Check that the product and system are free of air; bleed if needed – see the section Connecting the brine system.

• Check that the brine system is still pressurised and that the fluid level in the brine vessel is adequate/correct.

• No annual leakage control of the refrigerant is required.

7.2 Shut-down

The heat pump is shut down using the operating switch. If there is a risk of the water freezing, drain out all the water.

7.3 Service position


General Information

8. Troubleshooting/appropriate measures

The heat pump is designed to provide reliable operation and high levels of comfort, and to have a long service life. Various tips are given below which may be helpful and guide you in the event of an operational malfunction.

If a fault occurs, you should always contact the installer who installed your unit. If the installer believes the malfunction is due to a material or design fault, then they will contact CTC-UK to check and rectify the issue. Always provide the product’s serial number.

8.1 Air problems

If you hear a rasping sound from the heat pump, check that it is properly bled. Top up with water where required, so that the correct pressure is achieved. If this noise recurs, call a technician to check the cause.

8.2 Alarms

Any alarms and information texts from the heat pump are displayed in the product which is used to control it or CTC Basic Display; you should therefore consult the manual for that product to identify the alarm codes.

8.3 Noise/vibrations

When starting up the compressor a loud noise and vibrations may occur.

This lasts for a few seconds and should then subside. If the noise does not disappear, contact your installer.

8.4 CTC Basic Display

If a fault occurs with the EcoLogic display, values from the modules can be read using the CTC Basic Display. Basic Display can also be activated as a controlling unit. See the manual for the CTC Basic Display.

8.5 Safety risk

CTC EcoPart must never be used as a shelf. Nothing should be placed on top of or next to it, leaning against the product/pipes.

8.6 Display “Lockout”

Occurs if the EcoLogic Display has frozen in some way and does not respond to the buttons being pressed. Wait a moment and try again; if you do not get any response you can cut the power via the switch as a first measure. Wait approx. 10 seconds and turn the power back on. If the phenomenon does not disappear, contact your installer.
